The run down is a 04 6-speed with the stock hu, upgraded front and rear speakers in door and rear deck. They are sony's. Bought a pioneer 4-Channel Amplifier (GM6300F) cause I got a good deal on it. It has speaker level inputs built onto the amp. However I keep hearing about using an loc and running rca's to the amp. I am not sure which one I should do. I am not going to get it pro installed. I would rather do the work myself and know that I am doing it correctly. No matter how long it takes me. The amp will be powering the Sony's. I don't want a sub or any big bass. I have a 10 month old little girl that rides with me and a little boy that will be here in a few months. :baby: The reason for me doing the amp is because I want more sound out of the speakers. When I am driving on the interstate with the windows down I cant hear it as well as I want to. Back to the matter, I can easily tap into the rear speaker wires from the 6x9's. I then want to run new 16 guage wire to the speakers in the front and the rear. I also want to take and get some new dome tweeters(not decided on brand yet. Your opinions would help) and mount them on the door pointing my direction and disconnect the POS factory tweeters that barely make any sound. The new dome tweeters would be hooked to the stock hu. What would you do with the install? Getting a new hu is out of the question and budget. Kids taking all my damn money already.
